How does that even work? Does the phone just never truly power down? Can they track it even if they battery is dead?

- autoexec 2y agoI doubt they can if it's it dead, but as long as it has some charge the chips in your phone can use it without any indication to you.
- datadrivenangel 2y agoSome phones when turned off would power on every ~10-15 minutes or so to check for text messages, which effectively pings cell phone towers.
- thrwaway1985882 2y agoSquint enough and you'll see a cellphone consists of two primary chipsets: a main SOC/stack that runs the operating system, and a modem/software stack that pushes cell packets. Power the phone down and you (may) fully shut down the OS/processor; you likely aren't powering down the modem.
